Superior Thermal Performance

Our double-glazed windows and doors are designed to provide top-notch performance, keeping your home at a comfortable temperature all year round while preventing heat loss. With double glazing, we can reduce the amount of heat escaping from your windows by 50%. Double glazing consists of two panes of glass filled with argon gas, creating an effective thermal barrier between the inside and outside of your home. Achieving U-values as low as 0.8 W/m²K, you can enjoy a more comfortable home while reducing your energy consumption, and ultimately, your energy bills.

An Extra Layer Of Protection

As well as being incredibly efficient, double glazing is also highly secure. The extra layer of glass makes it tough for unwanted visitors to break in. As standard, our high quality windows and doors come fully equipped with multipoint locking systems and quality hardware. With our highly secure windows and doors, you can enjoy complete peace of mind knowing that you and your loved ones are protected from any unwanted visitors.

Effective Acoustic Insulation

Double glazing also offers fantastic noise insulation. Double glazing helps to block out external noise by the two panes of glass and the gas between them being able to absorb the sound vibrations and dampen the transmission of sound.
